The passengers onboard a 12-person Dassault Falcon 900B were traveling at nearly 500 mph, yet they still had only 1 second to witness the totality, or the moment during a total solar eclipse when the moon entirely obscures the sun and ushers in a special kind of darkness across a narrow track 100 miles wide on the Earth's surface.

A standard total solar eclipse occurs roughly once every 18 months. However, the next hybrid eclipse isn't slated to occur until 2023. The next non-hybrid, total solar eclipse isn't until March of 2015.

"We only had a second of opportunity. If we were another second off, we wouldn't have gotten an eclipse," Cooper said. "You have to be on the path to see the total eclipse. Anywhere else you'll just get a partial one," he added.

That meant flying a perfectly timed route from Bermuda across the Atlantic, chasing the shadow of the eclipse as it shot across the surface at roughly 8,000 mph. The eclipse typically slows down on to the middle of the its path, equalling more than 1,200 mph, or the the speed of the moon's orbit -- about 2,288 mph -- subtracted from the speed of the rotation of the Earth.

Cooper did concede that the debate is ongoing on whether or not he and the crew experienced totality in that 1-second time frame, or came right on the edge. Totality, he explained on his Web site, lasted for roughly 99 seconds over the ocean west of Gabon, a much smaller amount than a typical total solar eclipse.

Eclipse chasing is an age-old activity and has become increasingly more sophisticated as aviation and photographic technology has advanced. Chasers in 1973 utilized the maximum speed of a modified Concorde airliner to keep up with the speed of an eclipse's shadow for 74 minutes, cruising at nearly 1,500 mph across sub-Saharan Africa. Now, much smaller groups of hobbyists can take to the skies in cheaper, albeit slower, aircrafts to partake in the chase.

Due to the spiritual nature some attribute to syzygy -- the term for when three celestial bodies align -- and the perception among ancient cultures that such events were supernatural, total solar eclipses have become worldwide celebrations worthy of multiday treks and cross-continent exploration. In December of 2002, 40,000 people ventured to the Australian outback to witness one.

For Cooper, who has photographed nearly every astrological phenomenon under the sun and beyond, a usual once-in-a-lifetime event for most people has meant four solar eclipses. The November 3 hybrid solar eclipse was his first viewed from an airplane.

"I was shooting about seven frames per second," he said, noting that modern-day digital cameras are so advanced that no special add-ons are needed to capture such an event, which typically requires special eye protection for viewing from the ground. Cooper used a telephoto and wide-angle lens to achieve the photographs. "Getting the photos right in terms of light, it was definitely not easy," he added. "There was absolutely no time to adjust."
